I had a well-rounded workout at the gym yesterday, which included some time on the stationary bike, the elliptical, some upper body strength training with dumbbells, and a little bit of core work. I don't feel as sore this morning as I expected to. Either I've gotten stronger or I need to push myself a little bit harder. Maybe a bit of both.
I tried a new elliptical machine there at the gym, one with a TV screen, but the mileage was quite off from another elliptical machine I normally use there. After 7 minutes, it said I'd only gone 2/10 of a mile! I'm slow, but usually go more than twice that speed on the elliptical. I got off that one (the TV screen turned out to be a nuisance anyway!), went to do something else, and hopped on my normal brand of elliptical machine (sans TV), and had a good workout there.
I still have my eye on the half marathons in March and April (and hopefully May), but am enjoying my time in the gym for now, especially during this cold weekend here in central North Carolina.
